There is a road that runs north and south on the island. The city of Memphis dumped/piled sand and gravel on the two lanes on the river side of this road, just in case the water rose enough to cover the road. The northern end of this road has been underwater for about a week, so presently, this southern end is the only access on and off the island, where many people live.
Above, I am standing on the driveway to one of the parking areas, which is submerged behind me.
Below, water, water everywhere!
